Hillsdale Station is also served by Samtrans' All Nighter Route 397, an all-night bus service connecting San Francisco, Brisbane, South San Francisco, San Francisco International Airport, and the El Camino Real corridor between Millbrae and Palo Alto Caltrain via East Palo Alto.[4]

Until December 20, 2005 the former Bay Meadows Racetrack had the now-closed Bay Meadows station, less than a half-mile (800 m) north of Hillsdale. When Hillsdale was renovated the platform was extended a few hundred feet to the north, eliminating the need for the separate station. Hillsdale is now the closest station to the former racetrack area.
